Medium Nessus Plugin ID 35816
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200903-18 (Openswan: Insecure temporary file creation)
Dmitry E. Oboukhov reported that the IPSEC livetest tool does not handle the ipseclive.conn and ipsec.olts.remote.log temporary files securely.
A local attacker could perform symlink attacks to execute arbitrary code and overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll Openswan users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/openswan-2.4.13-r2'
